ELECTRONIC SIGNALS
The AMT Series Multitone electronic signals provide
the industry with a UL 1638/464 combination
Audible/Visual device that simplifies installation and
offers three (3) distinct prioritized audible signals from
three (3) isolated inputs. Priority one (1) will override
all other command upon activation. The AMT offers a
choice of eight (8)self-prioritized sound outputs from
which the three (39 prioritized sounds are selected.
(See Table # 1 for the various sound selections.)
The AMT and AMT Strobe units have two (2) user selective
sound output levels, standard dBA and high dBA.
The AMT provides dual voltage capability in one unit,
12V DC or 24V DC operation, filtered or FWR. The
AMT Strobe electronic signals operate with either 12V
DC or 24V DC and may be used with filtered or unfiltered (full-wave rectified) input voltages. Separate
supervised sets of input terminals are available for each
prioritized input. Jumper plugs are provided to enable
both tone and strobe to operate simultaneously for all
inputs. The AMT and AMT Strobes are UL listed for
indoor and outdoor, using appropriate back boxes.
FEATURES
• Three separate prioritized inputs that will activate
three isolated signals
• All inputs can be supervised
• Two power taps for high dBA and normal dBA
at 10 feet
• Low current draw with low temperature compensation
to reduce power consumption and wiring costs
• AMT Strobe models available in 12V DC with 15
candela strobe and 24V DC with 15 or 117
candela strobe
• AMT with strobe can flash independently or in
unison with audible signal
• Low cost installation via standard electrical boxes.
Attractive flush or surface mounting options
• Listed under UL Standard 1638 for visual
signaling and UL 464 for audible appliances,
indoor and outdoor
APPLICATIONS
Industrial signaling where separate signals are
required, such as pumps and motors, and conveyor
systems.

1Strobe candela at 35˚ Centigrade is reduced to
7.5 candela for WH models and 78 candela for
WM models.
The UL Listed “Rated Input Voltage”is 20-31 VDC
for AMT-24-WM, AMT-24-WH and 12VDC for
AMT-12-WH using either filtered (DC) or unfiltered
full-wave-rectified (FWR) voltage. Check the minimum and maximum output of the po wer
supply and standby battery and subtract the voltage drop from the circuit wiring resistance
to determine the applied voltage to the strobes .

1.Add 25% more input current when operating 24 VDC models at 31 VDC
2.Add strobe current from Table 1 to audible signal current from Table 2 to obtain total current for each unit, if the strobe and audible are wired to operate in unison
on a single circuit.

Anechoic dBA is measured on-axis in a non-reflectiv e
(free field) test room using fast meter response .
For peak dBA (measured with peak meter response)
add 5 dBA to anechoic values shown in Table 3.
Reverberant dBA is a minimum UL rating based on
sound power measurements in a reverberant test room.
